renrenfast-vue与node12不兼容的问题

刚开始以为是 node 或 npm 版本问题，前前后后折腾了好久，终于解决了

2|0解决：

如果执行过npm install，先删除 node_modules 文件夹，不然运行的时候可能会报错
执行下面的命令

npm install chromedriver --chromedriver_cdnurl=http://cdn.npm.taobao.org/dist/chromedriver

再执行 npm install 即可正常下载

3|0分析：

经分析发现，某些版本下，chromedriver 的 zip 文件 url 的响应是 302 跳转，而在 install.js 里使用的是 Node.js 内置的 http 对象的 get 方法无法处理 302 跳转的情况；而在另外一些情况下，则是因为 googleapis.com 被墙了，此时即使采用科学上网的方法也仍然无法获取文件。

Node-sass is a library that provides binding for Node.js to LibSass, the C version of the popular stylesheet preprocessor, Sass.

It allows you to natively compile .scss files to css at incredible speed and automatically via a connect middleware.

Find it on npm: https://www.npmjs.com/package/node-sass

Follow @nodesass on twitter for release updates: https://twitter.com/nodesass

Install

npm install node-sass@4.9.0

Some users have reported issues installing on Ubuntu due to node being registered to another package. Follow the official NodeJS docs to install NodeJS so that #!/usr/bin/env node correctly resolves.

Compiling on Windows machines requires the node-gyp prerequisites.

Install from mirror in China

npm install -g mirror-config-china --registry=http://registry.npm.taobao.org
npm install node-sass
npm install node-sass@4.9.0 --save

Usage

var sass = require('node-sass');
sass.render({
  file: scss_filename,
  [, options..]
}, function(err, result) { /*...*/ });
// OR
var result = sass.renderSync({
  data: scss_content
  [, options..]
});

Options

file

Type: String
Default: null

Special: file or data must be specified

Path to a file for LibSass to compile.

data

Type: String
Default: null

Special: file or data must be specified

A string to pass to LibSass to compile. It is recommended that you use includePaths in conjunction with this so that LibSass can find files when using the @import directive.

nodej版本10以上，NODE_MODULE_VERSION 6

而工程下的node-sass版本为4.5.3，最高支持的版本NODE_MODULE_VERSION为57，无法支持node10版本NODE_MODULE_VERSION64

所以执行npm install 会出现类似的情况

Cannot download "https://github.com/sass/node-sass/releases/download/v4.5.3/win32-x64-64_binding.node":
HTTP error 404 Not Found
因为node-sass4.5.3 不支持node10， node10版本NODE_MODULE_VERSION 64，这文件就是不存在的，下载不下来。
